Not very helpful in this situation, but FontForge has a non-standard

That would perhaps not be a bad idea. If that table is there then
luatex will automatically use it (it is a subtable of 'TeX ', which
also contains height and depth information, and font dimensions).
so, that data would end up in a regular feature/lookup? of is it an
entry in the glyph?
They are automatically merged into the glyph, as
glyph.italic_correction
glyph.tex_height
glyph.tex_depth
Hi,
Considering current state that we don't know any fonts that has ITLC table,
it would be better than nothing to implement italic correction as follows.
Per FontForge's documentation, it can generate italic correction values,
may be LuaTeX could make use of such feature and provide a way to
generate italic correction values for fonts missing it, may be the tex
height and depth too, if it isn't doing so already? Since FontForge has
access to actual glyph shapes, it might be generating better guesses.
I can generate sample fonts with FontForge for testing, if needed.
as such an italic correction is not part of the font design but a guess
it makes sense to keep it 'under lua control' so i implemented a
itls=yes feature (base mode and node mode; is in beta)
